If money be spent on the elderly, not on robots, it's unlikely that the elderly will always be used because they will become weaker and weaker even without the strength to go to the market to buy vegetables to cook or be cheated of money,... so i think spending money on robots to support the elderly is good. In my opinion, it is better to invest in the production and training of robots to help the elderly even though they have many disadvantages. I know robot has its own drawbacks but robot have many benefit such as: when robots can be used both in homes and in other areas, it could improve the standard of living of people. House hold chores took significant cut in humans' life. In short, spending money on robots to help the elderly will help them more.
